Patent DE-3109943-A1 (DE)
Title: Self-closing valve controlled by a permanent magnet
Inventor: ROTTER DIRK
IPC: F16K31/08
Filed: 1981-03-14
Abstract: In a self-closing valve controlled independently of the medium by means of a permanent magnet, a compressive movement upon actuation of the valve is converted by means of a tappet-like component and an axially displaceable sliding block into a rotary motion of a threaded spindle which winds up a mechanical clockwork mechanism. Via a cam mechanism and the permanent magnet, the valve is opened in a known manner by the pointer shaft of the clockwork mechanism while the said mechanism runs down. To adjust the run-down time, the guide of the sliding block can be rotated by small angles in the top part of the valve housing by means of a pinion gear.

Patent DE-3115714-A1 (DE)
Title: Drum pump with electric drive motor
Inventor: GSCHWENDER ALOIS
IPC: H02P1/42
Filed: 1981-04-18
Abstract: Drum pumps consist of an electric drive unit with pump tubing flanged thereonto, whose shaft carrying the impeller projects from the tube in a sealing manner, to which end slide ring packings are provided. Owing to the considerable length of the shaft (up to 3 m at a diameter of 6 mm), the torsional load during start-up of the pump results in considerable shortening of the shaft, owing to which the axial sealing faces of the slide ring packing lift off from one another, as a result of which liquid is able to penetrate into the interior of the pump tubing, possibly even into the drive unit. According to the invention, a control appliance (4) integrated in the housing (6) of the drive unit (1) (Figure 1) is provided which prevents start-up of the motor (3) above the nominal current, i.e. with an overload. Owing to this "gentle start-up" the stress on the individual components such as motor (3), clutch (20), bearings and shafts (8, 21) is reduced, so that the service life of the drum pump is increased. The tightness of the sealings provided is now ensured even during start-up of the drum pump, so that damage to the drum pump due to penetration of liquids, in particular when pumping aggressive media, is reliably avoided. In an advantageous refinement of the invention, the control appliance (4) is designed to control the motor speed, and the motor protection circuit is integrated in the control appliance (4). <IMAGE>

Patent DE-3147968-A1 (DE)
Title: System for manufacturing circular and other lacy paper from paper webs
Inventor: JENSEN BERND
IPC: B26D7/18
Filed: 1981-12-01
Abstract: The machine production of lacy paper has previously been restricted to the embossing and stamping of the paper web coming from an unwinding station. The transverse cutting of the paper web and severance of the links joining the lacy paper to the rest of the paper web takes place by hand. This is not efficient in any respect. However, an important deficiency in the previous manufacture is to be seen above all in the fact that the lacy paper used solely as a doily for food, such as cakes and the like, can be rejected with regard to food legislation as a result of the contact by hand. By means of the invention, the work done by hand is to be replaced by a further machine station. According to the invention, this object is achieved in that the paper web (14) passes from the embossing station (20) into a cutting station (15) which comprises two or more cutting cylinders (16), fitted with radial separating cutters (17, 18), and pressing-on cylinders. <IMAGE>
Patent DE-3147987-A1 (DE)
Title: Three piston high pressure pump with swashplate drive
Inventor: SCHULZE WERNER
IPC: F04B1/14
Filed: 1981-12-04
Abstract: In the case of a three piston high pressure pump with swashplate drive and three pistons displaceable parallel to the axis of rotation of the swashplate, immersing in pump chambers and displaceable in a reciprocal movement by the swashplate, two of which pistons are arranged at the same radial distance from the axis of rotation of the swashplate, in order to reduce the overall dimensions and to guarantee the same pressure ratios on all three pump chambers in a horizontal arrangement it is proposed that the third piston be at a smaller distance from the axis of rotation and be arranged, in a circumferential direction, between the two outer pistons and that the swashplate have an outer, annular sliding surface, which is assigned to the two outer pistons, and a central sliding surface, which is assigned to the inner piston and is inclined in the opposite direction in relation to the axis of rotation compared to the other annular sliding surface.
Patent DE-3150537-A1 (DE)
Title: Mixer machine with split mixer shaft for horizontal working on the vessel in order to enable a mechanical seal to be exchanged by means of a central lifting device
IPC: B01F15/00
Filed: 1981-12-21
Abstract: The currently constructed mixer machines are rigidly fixed vertically or horizontally to the vessel. Their designs do not permit any exchange of mechanical seals during an uninterrupted mixing process in the vessel. To accomplish the exchange, the vessel will probably have to be emptied, the mixer machine must be dismantled from the vessel, the mechanical seal exchanged and reassembled into the machine with the vessel. During this time, the mixing process is completely interrupted. The invention permits a mixer to be installed vertically, horizontally or with an inclination on the vessel. If a mechanical seal is leaking, it can be exchanged by means of this lifting device. The exchange can then take place during the mixing process in the vessel. This eliminates the downtime. It should be noted that the installed protective sleeve separates the medium from the mechanical seal and the hub, so that the operating life of a mechanical seal is additionally extended. A connected pH meter signals when the medium in the protective sleeve is contaminated, and it includes a small water pump for washing the contaminated medium out with water. The split mixer shaft and the lifting device permit the exchange of mechanical seals. No mixer machine having these properties has hitherto been developed.

Title: Control for a model track system, particularly for a model railway
Inventor: HOETZSCH FRIEDRICH
IPC: A63H19/24
Filed: 1982-01-27
Abstract: In a control for a model track system (1), particularly a model railway, comprising a multiplicity of switches (W1...) and signals (S1...), which can be operated in a defined mutually harmonised manner via control lines (4), an audio tape device (16) is provided, on the magnetic tape of which a pulse pattern without DC component, representing the sequence and duration of operation of the switches and signals, is serially recorded. The pulse pattern is converted via first switching means (17, 12, 14) into switching pulses for the switches and signals for the correct control line in each case. In addition, the control system can be designed in such a manner that control commands given manually to the switches and signals are simultaneously supplied to the magnetic tape of the audio tape device (16) via second switching means (10, 11, 13). A normal cassette recorder is preferably used as audio tape device. This control system allows a schedule for a model railway to be changed in a simple manner without rewiring and program changes. <IMAGE>

Title: Firing aid
IPC: C04B33/32
Filed: 1982-05-19
Abstract: In a firing aid for firing flatware parts such as plates, cake plates or the like, consisting of a carrier surface which takes up the base of the flatware part to be fired and which rises obliquely upwards underneath the rim of the flatware part to be placed thereon and, at its edge, is bent downwards to form a base part of preferably reinforced design, the carrier surface is lowered downwards in the region located within the base of the flatware part to be placed thereon, for the purpose of avoiding stresses and cracks in the carrier surface or at the level of the crank due to the loading with the plate standing on the carrier surface and, in conjunction with this, due to the heat accumulation below the bases of the plate during firing of the flatware parts in the kiln. The lowered region is then expediently located at the level of a plane in the middle between the plane of the carrier surface and the standing plane, defined by the base ends, of the firing aid. The transition zone between the lowered region and the carrier surface can extend obliquely outwards and upwards.

Title: Barred-window imitation
Inventor: HERRE KLAUS
IPC: E06B3/68
Filed: 1982-08-31
Abstract: Window bars are traditionally offered in a wooden version by the relevant trade and represent a component of the whole window. Correspondingly, glass used for this is cut to the size of the available recesses, inserted and puttied or secured internally by strips. In the present technical operation, the bars can be installed subsequently. The barred-window imitation is simply placed on the insulating glazing, which is today frequently present, and is anchored on the frame according to my present drawing. Any window can be subdivided to any size by the "cross insertion connection part" in injection-moulded plastic form. This matter of concern arises in particular today in the modernisation of old houses. In general, those responsible for the protection of historical monuments regret that, in a case of good restoration, for the most part the windows are the only structural element to turn out stylistically incongruously. All previous efforts in this area were not satisfactory as they are either solved traditionally and thus cost-intensively or internally and thus stylistically incongruously. Every craftsman or handyman can use and subsequently instal this solution today.
